Great art starts with great products. Louis Prang developed child-safe art products that upheld the highest standards and quality in materials and color. These standards are maintained today in a comprehensive line of Prang art products for both children and professionals. The Oval-8 watercolor set was first introduced in 1856. Like all Prang watercolors, the paints are of the highest quality, made of pure pigments with no wax fillers. Preferred by teachers, the Oval-8 includes 8 classic colors in snap shut storage box. A white mixing tray and wood-handled brush are included. Paint oval strips are refillable.
